Spreadsheet Audit (Live)

Q: How do I know the Spreadsheet Audit (Live) output is good?

The skill verifies itself against its own quality checks: Formulas were read from the real file, not inferred from values; Every finding names an exact cell/range; Load-bearing outputs are each marked verified or suspect (none silently assumed); The original file was not modified; any corrected copy is a new file with a change log.

Audit the user's REAL spreadsheet by opening it in the Cowork sandbox — not by reading a description of it. Use when asked to check this sheet before we present it, audit the model in my Drive, why don't these numbers add up, or is this spreadsheet safe to build on. Pulls the file via the Google Drive connector (or an uploaded .xlsx), opens it programmatically in the sandbox to trace formulas, hunts hardcodes / broken ranges / unit mixes, and produces a ranked findings artifact with a verified-vs-suspect ledger and a fix list.

🗣 Say this to your agent

“Audit the budget model in my Drive before the board call.”“Check this spreadsheet — why don't the totals add up?”“Is this sheet safe to build on? Open it and trace it.”“Someone left me this model; hunt it for hardcodes in Cowork.”

What to give it

▸The sheet — a Drive file/link or an uploaded `.xlsx`; the audit needs the real formulas, not a screenshot

▸The stakes — what decision it feeds (budget approval? pricing? a board number?) — depth and ranking follow the damage potential

▸Growth pattern — does data get appended? The fragility check keys on it

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Formulas were read from the real file, not inferred from values

✓Every finding names an exact cell/range

✓Load-bearing outputs are each marked verified or suspect (none silently assumed)

✓The original file was not modified; any corrected copy is a new file with a change log

✓The verdict follows the findings, not optimism

⚠️ What it refuses to do

**Auditing the screenshot** — open the actual formulas.

**Overwriting the source** — corrections go to a copy.

**Claiming "looks fine"** without tracing the headline numbers.

**Cosmetic tidying** dressed up as an audit — protect the decision, not the formatting.
